Liquid Flow Sensor serves low-volume dosing applications.

Able to detect flow rates below 120 mL/min for hydrocarbon-based liquids, SLQ-QT105 offers ~40 msec measurement response time and sensitivity for flow rates down to 3 mL/min. Detection of air bubbles in Â-µL range is also possible, and all wetted materials are made from PTFE or quartz glass. Flow is measured without moving parts and non-invasively through wall of straight flow path. Features...
